Any good English books similar to the German [WayBack] Agiles Coaching by Judith Andresen [Leanpub PDF/iPad/Kindle]?
Although my German reading is quite OK, it’s not OK enough to fully use this book.

Especially important for Delphi users on Windows 10 Creators Update: IDE Fix Pack 6.1 released | Andy’s Blog and Tools
Posted by jpluimers on 2017/10/31
The new [Archive.is] IDE Fix Pack 6.1 released | Andy’s Blog and Tools is huge, especially for Windows 10 targets:
Windows 10 Creators Update 1703 caused issues with all Delphi programs, libraries and packages because it changed how Windows loads imported DLLs in such a way that it causes performance issues and can crash the debugger.
Delphi 10.2 Tokyo Update 2 fixed this by not producing multiple dll import sections for one DLL anymore.
IDE Fix Pack 6.1 implements that “feature” for all previous Delphi versions (2009-10.1 Berlin) and extends it to not only eliminate duplicate dll imports but also duplicate delay dll imports.
There are also (optional) updates that you can enable with new compiler switches:
- Eliminating
fwaitinstructions (but be careful, as they can confuse the debugger) - Optimising calls to virtual methods through interfaces
- Optimising certain function prolog code
There are some smaller changes too.
I’m going to try this soon.

Firebird – generate time/date/timestamp values
Posted by jpluimers on 2017/10/31
I needed the script in [WayBack] Firebird – generate time/date/timestamp values to reproduce a problem in Database Workbench <= 5.3.2 with exporting TIME and TIMESTAMP values to Excel xlsx format: the time portion got lost so
- TIME columns all became a date
1900-01-00(I think the00is because of the infamous 1900 problem that also makes this hard: Excel worksheet function – How do I get the weekday name of a date?) - TIMESTAMP columns all got the midnight timestamp of the date value specified
The bug is fixed so will appear in the next beta and release versions: [WayBack] 0001506: Timestamp export to Excel XLSX only shows date, Time fails, CSV shows both date and time – Bug & Feature Tracker @ Upscene.com

Until someone writes proper string visualisers for the Delphi debugger…
Posted by jpluimers on 2017/10/31
A few tricks to write long strings to files when the Delphi debugger cuts them off (just because they like using 4k buffers internally);
TStringStream.Create(lRequestMessage).SaveToFile('c:\temp\temp.txt')TIniFile.Create('c:\a.txt').WriteString('a','a',BigStringVar)TFileStream.Create('c:\a.txt', fmCreate or fmShareDenyNone).WriteBuffer(Pointer(TEncoding.UTF8.GetBytes(BigStringVar))^,Length(TEncoding.UTF8.GetBytes(BigStringVar)))
They all work form the debug inspector, but they do leak memory. See comments below.

Android app writers: How to lose your end-users’ notification privilege…
Posted by jpluimers on 2017/10/30
Android apps make sounds when posting notifications. So adding useless gets you on the blacklist quickly thereby disallowing your app for posting any notifications at all.
Kristian shows how and why at
How to lose notification privilege:
- Use notification for marketing.
- Long press.
- Disable.
It’s that easy. You never force grab my attention for marketing a second time, especially since Android notifications by default come with sound now. This one woke me up.

How to connect S+DA0003 using SFP between MikroTikCRS226 and MikroTikCCR1009
Posted by jpluimers on 2017/10/30
Mikrotik and SFP versus SFTP+ is always confusing especially as the text on their equipment and their documentation doesn’t show well which situations work.
Equipment text is further on, this is their text searchable documentation:
- [WayBack]: Supported Hardware: SFP+ modules – MikroTik Wiki tells this:
-
Brand Model Distance Rate Connector/Cable type Wavelength Tested with Works / Doesn’t MikroTik S+DA0003 3M 10G Twinax Copper — All MikroTik products with SFP/SFP+ interfaces Natively supported
-
- SplusDA0003: This is highly cost-effective way to connect two SFP/SFP+ devices (for example two units of CCR1036-8G-2S+) for very short distances…[WayBack] RouterBoard.com : SFP+ 3m direct attach cable
As usually, a long search in the forums reveals the background information:
[WayBack] SFP in SFP+ slot – MikroTik RouterOS: 10Gb SFP+ sockets are usually backward compatible with SFP, but this is not guaranteed.
There are two tricks involved to get an SFP connection between these devices working:

ModMyPi | Cluster HAT Kit Inc. 4 x Raspberry Pi Zero
Posted by jpluimers on 2017/10/30
Interesting stuff; I wonder if there is a case for it as well:
The Cluster HAT interfaces a (Controller) Raspberry Pi A+/B+/2/3 with 4 Raspberry Pi Zeros Configured to use USB Gadget mode, it is an ideal tool for teaching, testing or simulating small scale clusters.
This Kit Includes 1 x Cluster HAT V2, 4 x Raspberry Pi Zero’s, 4 x 16GB Micro SD Cards.
Please Note. A Raspberry Pi B+/2/3, with SD Card & Power Supply are also required for set up. These items are NOT Included in the Kit but can be purchased separately.

Need to give this some thought: multi-LAN on Mikrotik
Posted by jpluimers on 2017/10/27
Maybe for my LoT (LAN of Things): having multiple (even many) local LANs some each with their section of LoT equipment nicely separated and partially being able to talk to some of the other LANs or part of the outside world.
Some links that might help me getting this set up:
- [WayBack] How to set up multiple networks on a Mikrotik router | Networking For Integrators
- [WayBack] Masqueraed and routing, few questions (multiple LAN, multiple WAN scenario) – MikroTik RouterOS
- [WayBack] Multiple Lan on single wan – MikroTik RouterOS
- [WayBack] Mikrotik RouterOS routing between subnets on local ports – Network Engineering Stack Exchange
The basic plan:
- Configure each port or grouped (with ethernet master-port or maybe bridged) of ports having their own address pool and DHCP server so each of them are in a separate private network
- Routes between the networks so they can be accessed
- NAT mangling so the networks can reach the other networks or outside world without exposing their private network addresses
- Firewall rules to permit/limit which networks can see each other or the outside world
WinBox displays routes in various colors [WayBack]:
- Black – active
- Blue – inactive
- interface not up or disconnected
- other route with higher precedence already covers this route
- Red – invalid
- interface does not exist
- interface is disabled
- IP address not on that interface any more
Sometimes they show as blue while still being legitimate. Not sure why yet.

OS X Mountain Lion and up: Zoom content on the screen
Posted by jpluimers on 2017/10/27
Accessibiity -> Zoom -> enable checkbox” class=”size-medium” /> Preferences -> Accessibiity -> Zoom -> enable checkbox
I didn’t know this was built-in since Mountain Lion and up, but it is, is startable from the keyboard and it’s tremendously convenient when presenting: [WayBack]: OS X Mountain Lion: Zoom content on the screen.
TL;DR:
- System Prefrecences
- Accesibility
- Zoom
- Checkbox
